Gratitude

Gratitude is an emotion expressing appreciation for what one has—as opposed to, for example, a consumer-driven emphasis on what one wants. Gratitude is getting a great deal of attention as a facet of positive psychology: Studies show that we can deliberately cultivate gratitude, and can increase our well-being and happiness by doing so.

Happiness

Ah, happiness, that elusive state. Philosophers, theologians, psychologists, even economists, have long sought to define it, and since the 1990s, a whole branch of psychology—positive psychology—has been dedicated to pinning it down and propagating it.
